Febrex Plus AF Syrup is a combination medication containing Chlorpheniramine Maleate (2mg/5ml) and Phenylephrine (5mg/5ml), formulated to provide effective relief from symptoms associated with allergic reactions and nasal congestion. Chlorpheniramine Maleate is an antihistamine that helps reduce allergy symptoms such as sneezing, runny nose, watery eyes, and itching by blocking the effects of histamine in the body. Phenylephrine acts as a decongestant, constricting blood vessels in the nasal passages to alleviate swelling and congestion, thereby improving breathing. This syrup is commonly used to treat conditions like common cold, hay fever, sinusitis, and other upper respiratory allergies. Febrex Plus AF Syrup is suitable for adults and children as directed by a healthcare professional and should be taken with caution in individuals with hypertension, heart disease, or thyroid disorders due to the stimulant effects of Phenylephrine. It is important to follow the prescribed dosage and avoid concurrent use with other sympathomimetic drugs or monoamine oxidase inhibitors (MAOIs). Side effects may include drowsiness, dizziness, dry mouth, or increased heart rate. Always consult a healthcare provider before use to ensure safety and efficacy.
